One customer at the fast food restaurant on Tuesday captured the melee on video.

The Tampa Bay Times reports some protesters wearing chicken and horse masks lay on the tile floors, while others pretended to stab them with bloody knives. Others lofted signs, and some screamed, “Animal killers!”

A Kissimmee woman who attended the protest said the goal was to protest how they think animals are treated in slaughterhouses.

“We went into to Chick-fil-A with the intent of only speaking on the animals, but we actually didn’t even get a chance to do our speak out because everybody got so aggressive so quickly.”

While customers looked on, yelling for the demonstrators to leave, some tried to shield their children from the fracas. Restaurant managers attempted to quell the disturbance.

Pinellas Park police were called but by the time they arrived all the protesters had fled.

No arrests have been made and it’s unclear what group was responsible for the flash protest.
